Basic film restoration-ish GUI - does this exist?

[Lyris]

Hey forumers. Say I have these image sources - a not uncommon scenario when dealing with film content, I imagine:

file 1: unprocessed
file 2: processed with mild dirt filtering
file 3: processed with heavy dirt filtering

And I want to chop and change between them - for example, reverting to 1 unprocessed in cases where the dirt filtering creates artefacts, or going to file 3 near reel changes. And also, mixing and matching wihtin a frame, for example using file 2 mostly, but reverting back to file 1 (unprocessed) in certain regions where the automatic filtering has erased genuine details.

Does such a tool exist? I seem to remember there being a free thing that resembled VirtualDub that would allow something like this, but my memory might just be playing tricks on me. I ask because I've trialed a bunch of film restoration tools, and frankly there's not been one that checks all boxes so far.

Not tested at all [You have to supply eg VeryHiDN() functions].

EDIT: Oops, squashed bug
